I will be installing a shower against a wall in a room that currently
has no mechanical extraction. I'm going to put a SELV fan adjacent to
the top of the enclosure. Directly beneath it, a foot or so off the
floor, is a large air brick. As an alternative to braying another hole
through the gable end cavity wall, is it practical to take a
rectangular duct down the wall, to exit through the air brick? Can
vapour be ducted downwards and outwards like this? If it can, would it
be better to have the fan at the bottom, where the brick is, and the
duct inlet at the top?

Any help that the group can provide will be much appreciated. It will
save me a lot of faff if I don't have to start braying more holes.

Cheers

all thats needed is airflow. All that needs to happen is 2 holes and 1
fan.
